Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531980, here are decompositions:

3 + 33531977 = 33531980
61 + 33531919 = 33531980
67 + 33531913 = 33531980
103 + 33531877 = 33531980
127 + 33531853 = 33531980
199 + 33531781 = 33531980
367 + 33531613 = 33531980
421 + 33531559 = 33531980

Showing the first eight; more decompositions exist.
